People who don't like them need to see the bigger picture
Back in 1948 after the end of World War II Britain had to set around rebuilding itself. Britain appealed to and welcomed roughly 50000 West Indian immigrants who left the Caribbean and went to England to work; they were welcomed at the time because their labour was going to help rebuild England. So they lived in England and worked in England over the last sixty years.
After the crash of 2008, the wages of British people has lowered, and as a result of Brexit the economic system is now about to implode. Someone had to be responsible for all of this and blaming immigrants was the achievement of the Theresa May government. As Home Secretary and as Prime Minister Theresa May has waged a war against West Indian immigrants. She went so far as to say that if one of those West Indians, men or women, couldn't come out with five or six documents to prove they were in the country illegally after fifty to sixty years of labour, rebuilding England, they would be deported and some were, and many were threatened with it.
It is strange that Polish immigrants still entrust their future to such ungrateful country.
